PRODUCT SUMMARY
This National Geographic program reveals breathtaking imagery and uses aerial laser surveys to capture redwoods trees in their natural environment. Humboldt State University researcher Steve Sillett studies the redwoods' biological material, physical features such as their crowns and new record-breaking trees. In addition, National Geographic explorer Mike Fay examines the range of redwood trees, which are being threatened with extinction in California.
